1. Introduction

ALTO MISTRAL amplifiers are series of innovative design power amplifiers. This series work

under high stability with great power supply in just 2-rack spaces. Air flow is from back to front

panel to keep in a nice air circulation inside the Rack. The automatic fan, which affects machines’

temperature includes various kinds of speed, therefore, this low-noise fan makes a good result in

cooling the heat from machines.

MISTRAL amplifiers include 2 independent channels with separate protection system and

power supply. The independent protection system avoids opening circuit, short, wrong loading or

over-heating. The special-designed protective system applies automatically restarting functions

upon the default status and then goes back to normal.

All electronic inputs equip standard power connectors. And all inputs are electronic balanced,

with hi-quality transformer, MISTRAL amplifiers provide an outstanding performance in any

conditions.

zInnovative design and high stability power amplifiers.

zFan-cooled AB class high power amplifier in 19”rack, 2Usize

zRugged amplifiers in a strong, compact chassis.

z2 independent channels with separate protection system and power supply

zsmart-designed protection system for auto re-operation after fault.

zAuto-adjusting speed fan.

z4LEDs for operation/protection, limit, power on and clip

zHIGH-CURRENT TOROIDAL TRANSFORMER DESIGNED FOR HIGH POWER AT 2

Ohms with low noise.

zIndependent DC and thermal overload protection on each channel.

zIEC standard power connectors.

zBinding post and NEUTRIK® SPEAKON outputs power connectors.

zBalanced XLR inputs/ parallel outputs.
